Which of the following best exemplifies homologous chromosomes?

Question

Quizplus · Accepted Answer

Homologous chromosomes refer to a pair of chromosomes that have similar genes at the same loci but may have different alleles. During prophase I of meiosis, homologous chromosomes pair up and form a structure called a tetrad, where they undergo crossing over, which leads to genetic variation. A pair of sister chromatids attached at the centromere refers to a single duplicated chromosome. The unpackaged DNA does not form a specific structure, and the mitotic spindle is a cellular structure involved in cell division but not in homologous chromosome pairing.
